During interphase, the cell grows and makes a replica of its DNA. During the mitotic (M) segment, the mobile separates its DNA into units and divides its cytoplasm, forming new cells.
During interphase, the cell grows and DNA is replicated. During the mitotic segment, the replicated DNA and cytoplasmic contents are separated and the mobile divides. In the eukaryotic cell cycle, chromosome duplication happens in the course of "S segment" (the segment of DNA synthesis) and chromosome segregation happens in the course of "M segment" (the mitosis segment). The S segment (or synthesis segment) is a length of the cell cycle in the course of which DNA is replicated (or synthesized). G1 and G2 are each increase phases, in the course of which cell organelles are replicated and the mobile grows in size.

Which nervous system controls the smooth muscles ?
Smooth muscle cells in the visceral organs are controlled by the autonomic nervous system, and muscle cell contraction or relaxation plays a significant physiological function in the control of blood pressure, motility of the digestive, respiratory, and urinary tracts, and secretion.
The nervous system is a highly complicated element of an animal that organizes its actions and sensory information by sending messages to and from many sections of its body. The nervous system monitors environmental changes that affect the body and then collaborates with the endocrine system to respond.
Around 550 to 600 million years ago, wormlike creatures developed nervous tissue. It is divided into two components in vertebrates: the central nervous system (CNS) and the peripheral nervous system (PNS) (PNS). The CNS is made up of the brain and the spinal cord.

Which virus Cannot replicate itself?
Option 1 is Correct. The fact that Trojan horse programmes do not replicate themselves makes them extremely different from real viruses. Trojans include malicious code that, when activated, results in data loss or even theft.
In particular, they are bits of genetic material (DNA or RNA) encased in unique protein coatings known as capsids. Viruses cannot reproduce unless they are taken up by our body's cells. Once a virus leaves the body, its capsid begins to deteriorate, and the more deteriorated it is, the less chance it has of surviving.
Virus (computer virus) (computer virus) A computer virus is a piece of malicious software that spreads by copying itself to another programme, the boot region of a computer, or a document, altering how a computer functions. Viruses spread between systems when humans get involved in some way.

Absorption is accomplished through the ______________.
Absorption is a process of diffusion, enabling molecules to move from areas of higher concentration to areas of lower concentration.
Driven by the kinetic energy of the molecules, this process naturally occurs and is used to absorb substances into a medium, such as a liquid or a gas. The rate of absorption is dependent on the concentration difference between the two substances and the size of the molecules, with smaller molecules diffusing more quickly and therefore being absorbed faster. Temperature also plays a role in the rate of absorption, as higher temperatures accelerate diffusion and therefore absorption.
Absorption is a crucial process in many biological and chemical processes, such as transporting nutrients, removing toxins and other harmful substances, and industrial processes, such as separating and purifying substances.

what embryos are used as the source for embryonic stem cells
The embryos being utilized in embryonic stem cellular studies come from eggs that have been fertilized at in vitro fertilization clinics however by no means implanted in women's uteruses.
The stem cells are donated with knowledgeable consent from donors. Embryos used as a supply of embryonic stem cells originate from blastocysts which are three to five days old. During the blastocyst stage, the cells are pluripotent, which means they could regenerate into nearly each form of cell. Human embryonic stem cells are derived from the internal cellular mass of the human blastocyst. Presumably normal (frozen/thawed) human preimplantation embryos that continue to be unused following assisted duplicate approaches have supplied the primary supply of blastocysts for stem cell derivation.

What is the appearance of the structure of a DNA strand ?
The structure of a DNA strand is a double helix, which is composed of two complementary strands of nucleotides that run in opposite directions. Each strand is composed of four types of nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
The nucleotides on one strand bond with their complementary nucleotides on the other strand through hydrogen bonds, forming the rungs of the ladder-like structure.
Adenine pairs with thymine, and guanine pairs with cytosine. The two strands are held together by these bonds, and the double helix twists around a central axis, forming a spiral shape. The double helix structure of DNA is stable and allows for the storage of genetic information and its replication.
The DNA double helix is often represented as a twisted ladder or spiral staircase with the nucleotides as the steps and the hydrogen bonds as the rungs of the ladder.
